STACK HEIGHT

A stack is often a part of the emission control equipment used to ensure low ground level concentrations. The effect of a stack is greatly affected by nearby buildings. This calculator estimates the required stack height based on the general guidelines described in Technical Support Document for Determination of Good Engineering Practice Stack Height , by the EPA

Building dimensions:

Stack height should be more than:

This tool allows the estimation of the stack height needed to respect a specified odour criteria at ground level. It also takes into account, in a simplified way, the height of the terrain surrounding the stack, or a nearby building within a radius of ten stack heights.This procedure can be applied to simple situations, however complex geography and/or the presence of many buildings requires a full dispersion modelling study to be conducted.
